Abstract

The present invention provides an integrated electric joint module, which includes: a shell, which is in the shape of a cylinder; a frameless servo motor, used to provide power, including: a stator and a rotor located outside the stator, and the rotor is rotatably arranged in the shell; The planetary reduction mechanism is arranged inside the stator, including the sun shaft, the planetary gear, the inner gear and the planet carrier, the sun shaft is connected with the rotor to rotate with the rotor, the inner gear is connected with the casing, and the outer wall of the inner gear is provided with a stator, and the planetary The frame is connected with the planetary gear meshingly arranged between the sun shaft and the internal gear, and is used as the power output end of the integrated electric joint module; the encoder is located in the shell and is set on the sun shaft; and the motor driver is located in the shell. Connect with encoder and stator. Through the above scheme, the structure of the joint module is compact, the external dimension of the joint module is reduced, and it has the characteristics of light weight and modularization, and is suitable for building various robots as a basic driving motion unit.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an integrated electric joint module. Background technique [0002] Along with industrial upgrading and the development of robot technology, modularization and lightweight have become the common needs and trends of various wheeled mobile robots, legged mobile robots, robotic arms, wearable robots and other robots. As an independent transmission unit and core component of the robot, the robot joint module determines the overall size, load capacity, motion speed and accuracy of the robot, and even the development cycle and life of the entire robot. [0003] However, in the prior art, high-speed, high-torque hollow motors, high-reduction ratio reducers, and high-power motor drivers are commonly used for high integration, making the joint module structure tend to be slender, focusing on speed and precision, while sacrificing part of the torque. For example, the leg joints of legged ro...
